Back up the file login.bat in the "MEDUSA4/master_project" directory (e.g. by copying it and renaming it login.bck)

Open the original login file and enter the following text directly after the line "...java/jre/lib/i386":
## added to access 32bit libraries
setenv LD_LIBRARY_PATH \
`edpath -a LD_LIBRARY_PATH /usr/lib32`

There may be others, and libs may be needed at run-time but the principle is the same - always download the 32-bit version. I didn't need to create any symlinks to make the installation work, at least as far as starting the application.

Im not sure that you will be succesfull since that ia32libs is no longer part of newer Ubuntu versions, and its repository mediubuntu was deactivated, unless youre trying to install TCE on an old version Ubuntu.
